Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0018] See also Figure 1-Figure 6As shown, the purpose of this embodiment is to provide an integrated machine for cleaning and collecting floating rust on the inner wall of a heating pipe, including a traveling frame 1, a traveling component 2 is installed at the bottom of the traveling frame 1, the traveling component 2 is used to drive the traveling frame 1 to move forward and backward, a cleaning component 3 for cleaning the inner wall of the heating pipe is installed on the top of the traveling frame 1, and a dust collecting component 4 for collecting impurities cleaned by the cleaning component 3 is arranged on one side of the cleaning component 3; The cleaning brush assembly 3 includes a driving motor 31, a transmission shaft 32 is installed on the conveying shaft of the driving motor 31, a clamping block 33 is fixedly installed on the outer surface of the transmission shaft 32, a shaft sleeve 34 is sleeved on the outer surface of the transmission shaft 32, a clamping groove 35 is provided on the inner wall of the shaft sleeve 34, the clamping groove 35 is clamped on the outer surface of the clamping block 33, a connecting rod 36 is installed on the outer surface of the shaft sleeve 34, a connecting assembly 37 is installed on the top of the connecting rod 36, a cleaning brush 38 is installed on the top of the connecting assembly 37, and the connecting assembly 37 can drive the cleaning brush 38 to telescope and adjust in the connecting rod 36; The dust collecting assembly 4 includes a collecting sleeve 41, a conical filter screen 42 is installed at one end of the inner wall of the collecting sleeve 41, a planetary gear set 43 is installed on the inner wall of the other end of the inner wall of the collecting sleeve 41, a connecting shaft 44 is installed on one side of the planetary gear set 43, and a fan blade 45 is installed on the side of the connecting shaft 44 away from the planetary gear set 43. The rotation of the fan blade 45 can make impurities be sucked into the collecting sleeve 41.
[0019] The drive motor 31 drives the drive shaft 32 and the shaft sleeve 34 to rotate, so that the dust collecting assembly 4 at the rear of the cleaning assembly 30 can be cleaned and the dust can be removed by the dust collecting assembly 4 at the rear of the cleaning assembly 30.
[0020] It should be noted that the walking component 2 is composed of a walking motor, a driving shaft, a walking driving wheel and a walking driven wheel. The walking motor drives the driving wheel to rotate through the driving shaft, thereby generating a driving force. The forward and reverse functions of the walking motor enable the machine to move forward and backward. The driving wheel and the driven wheel are made of steel core rubber-coated material to ensure that they can withstand sufficient rotational force and friction. At the same time, the polyurethane rubber layer has a certain shock-absorbing effect. The weld in the spiral welded pipe can effectively deal with the obstacles that may be caused to the normal movement of the machine. The internal structure connection of the walking component 2 is a prior art, and its working principle is common knowledge of the staff in this field, and will not be repeated here.
[0021] First, considering how the cleaning brush 38 is pressed against the inner wall of the heating pipe for cleaning, Figure 1 and Figure 4 , the specific structure of the connecting component 37 is disclosed. The connecting component 37 includes a sliding groove 301 opened at the top of the connecting rod 36, a telescopic rod 302 is slidably installed inside the sliding groove 301, a brush plate 303 is fixedly installed on the top of the telescopic rod 302, an extrusion spring 304 is sleeved on the outer surface of the telescopic rod 302, the top of the extrusion spring 304 is installed on the bottom of the brush plate 303, the bottom of the extrusion spring 304 is installed on the top of the connecting rod 36, and the brush plate 303 is fixedly installed on the bottom of the cleaning brush 38; the cleaning brush 38 can adjust the extrusion of the extrusion spring 304 by telescopic adjustment.
[0022] Four connecting rods 36 and cleaning brushes 38 are provided. The four connecting rods 36 and cleaning brushes 38 are located on the outer surface of the shaft sleeve 34 and are distributed in a circular array for cleaning the inner wall of the heating pipe.
[0023] Furthermore, by opening a sliding groove 301 at the top of the connecting rod 36, the telescopic rod 302 can be limitedly installed in the sliding groove 301 for sliding, and the brush plate 303 is installed on the top of the telescopic rod 302 to install the cleaning brush 38. The outer surface of the telescopic rod 302 is sleeved with an extrusion spring 304. When the all-in-one machine enters the heating pipe, the person presses the cleaning brush 38, and the cleaning brush 38 squeezes the extrusion spring 304 downward. The telescopic rod 302 drives the cleaning brush 38 to shrink toward the inside of the connecting rod 36, so that the circumferential diameter of the cleaning brush 38 is smaller than the heating pipe. After the cleaning brush 38 enters the heating pipe, the cleaning brush 38 is released, and the extrusion spring 304 is reset, so that the cleaning brush 38 is against the inner wall of the heating pipe to clean the impurities on the inner wall of the heating pipe.
[0024] Secondly, considering the problem of how the dust collecting component 4 collects the impurities swept, Figure 3 One end of the transmission shaft 32 away from the driving motor 31 passes through the collecting sleeve 41 and extends to the inside of the planetary gear set 43, so that the rotation of the transmission shaft 32 can drive the cleaning brush 38 to rotate together with the planetary gear set 43.
[0025] There are two planetary gear sets 43 , and the two planetary gear sets 43 are connected via a coupling, so as to achieve two-stage acceleration of the connecting shaft 44 .
[0026] Furthermore, the first planetary gear set 43 is connected via the transmission shaft 32, driving the sun gear on the inner wall of the planetary gear set 43 to accelerate rotation. The first planetary gear set 43 is connected to the second planetary gear set 43 via a coupling, and the sun gear in the second planetary gear set 43 is accelerated again, so that the connecting shaft 44 connected to the second planetary gear set 43 can drive the fan blades 45 to accelerate rotation, accelerate the airflow, form a pressure difference, and absorb the impurities scraped by the cleaning brush 38 into the collecting sleeve 41 for collection. The impurities enter the collecting sleeve 41 and are intercepted and collected by the conical filter 42, and the air circulates out normally, thereby achieving the effect of collecting the scraped impurities.
[0027] Again, considering how the integrated unit works inside the heating pipe, Figure 1-Figure 6 A camera module 5 is installed on the top of the traveling frame 1, and the camera module 5 is used to monitor the environment inside the heating pipe and the vehicle body.
[0028] Further, the camera module 5 can monitor the integrated machine, monitor the cleanliness of the inner wall cleaning, observe the welding defects of the inner wall of the pipeline, and monitor the balance state of the machine itself. It is mainly composed of a monitoring ball camera, a super five-category network cable, a small monitoring camera, a field optical cable, a photoelectric converter transmitting end, a photoelectric converter receiving end, a monitoring hard disk recorder, a mobile hard disk and a display. The camera module 5 is divided into two parts: one part is the ball camera at the front end of the machine connected by a super five-category network cable, and the signal is transmitted to the tail part of the machine through the conductive slip ring on the rotating shaft of the brush plate 303, and then the electrical signal is converted into an optical signal through the photoelectric converter, and transmitted to the monitor via the field optical cable, and the video is automatically recorded by the hard disk recorder. The other part is a small camera installed on the fuselage bracket, which observes the level meter on the bracket in real time, and converts the electrical signal into an optical signal through the photoelectric converter, and transmits it to the monitor via the field optical cable. When operating the machine outside the pipeline, it is necessary to observe the balance of the fuselage in real time and make adjustments at any time. The use of field optical cables effectively avoids the problem of the inner wall of the steel pipe shielding the electrical signal. The internal structure line connection of the above-mentioned device is the existing technology, and its working principle is common knowledge to the staff in this field, and will not be repeated here.
[0029] Finally, considering how to keep the cleaning brush 38 rotating and contacting the inner wall of the heating pipe when the traveling frame 1 is traveling, the following example is presented: Figure 6 There are two traveling frames 1, and the two traveling frames 1 are respectively installed at the bottom of the brushing assembly 3 and the dust collecting assembly 4.
[0030] Furthermore, the traveling frame 1 is divided into two parts, which are respectively installed at the bottom of the brush cleaning component 3 and the dust collecting component 4. The traveling motor installed on the top of the traveling frame 1 at the bottom of the brush cleaning component 3 can drive the wheels at the bottom of the traveling frame 1 to rotate through gears. The driving motor 31 is connected to the planetary gear set 43 through the transmission shaft 32, so that the traveling frame 1 under the brush cleaning component 3 moves, which can drive the traveling frame 1 at the bottom of the dust collecting component 4 to move together, so that when the device is moved and pushed, it will not affect the rotation of the cleaning brush 38.
[0031] It should be noted that during the operation, the traveling frame 1 cleans the inner wall of the pipe while traveling, and the friction generated will cause the traveling frame 1 to tilt. Therefore, a spirit level and a monitoring camera are installed on the body to monitor the tilt of the body and prevent the machine from tipping over in the pipe. In addition, in order to adjust the balance of the body, a crankshaft is installed at the driven wheel coupling, and a low-power motor is connected to one end of the crankshaft. The moving trajectory of the driven wheel is controlled by the forward and reverse rotation of the motor to achieve the adjustment of the balance of the body. The internal structure and circuit connection of the above-mentioned device is a prior art, and its working principle is common knowledge of the staff in this field, and will not be repeated here.
[0032] In summary, the working principle of this solution is as follows: The camera module 5 cooperates with the traveling assembly 2 and the traveling frame 1, so that the integrated machine can move smoothly in the heating pipe, so that the driving motor 31 can drive the shaft sleeve 34 on the transmission shaft 32 to rotate, and then the four cleaning brushes 38 installed on the outer surface of the shaft sleeve 34 clean the inner wall of the heating pipe, thereby achieving the effect of cleaning the inner wall of the heating pipe; A collecting sleeve 41 is installed on one side of the brushing assembly 3, so that the transmission shaft 32 can be connected to the planetary gear set 43 in the collecting sleeve 41. The two sets of planetary gear sets 43 accelerate the rotation of the fan blades 45 on the connecting shaft 44, so that the swept impurities can be absorbed into the inside of the collecting sleeve 41, and the conical filter screen 42 in the collecting sleeve 41 can intercept and gather the impurities for unified treatment.
[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
